Device and method for rapidly forming metal part through induction heating

Abstract

The invention discloses a device and method for rapidly forming a metal part through induction heating. The device comprises a base plate, a front heating unit and an induction smelting unit. The base plate is located below the induction smelting unit and used as a platform for metal part forming. The front heating unit is located between the base plate and the induction smelting unit and used for forming a uniform temperature field. The induction smelting unit comprises a support and a smelting crucible arranged on the support. An induction coil is arranged on the smelting crucible. The outlet end of the smelting crucible is provided with a smelting crucible nozzle opposite to the base plate. The inlet end of the smelting crucible is connected with an air inlet through a rubber plug and used for providing inert gas for the smelting crucible. The method is used for achieving induction heating and rapid forming of the metal part through the device. The device and method have the advantages of being high in machining flexibility, small in subsequent machining amount and the like.

Description

technical field [0001] The invention belongs to the field of rapid prototyping of metal parts, and more particularly relates to a device and method for rapid prototyping of metal parts by induction heating. Background technique [0002] The traditional manufacturing methods of metal parts are mostly subtractive manufacturing, such as turning, milling, planing, grinding, etc., or equal material manufacturing, such as casting, forging, stamping, etc. However, this method has disadvantages such as long development cycle, serious material waste, and difficulty in forming special-shaped parts. [0003] Rapid prototyping (RPM) technology, also known as 3D printing technology or additive manufacturing technology, is a comprehensive cutting-edge manufacturing technology that appeared in the United States in the early 1980s and developed rapidly in the world in the 1990s. It is an important part of advanced manufacturing technology . It is a technology based on digital model files ...

AI Technical Summary

Problems solved by technology

[0004] At present, the heat sources used in the rapid prototyping of metal parts are mostly lasers, such as selective laser sintering, selective laser melting or high-energy particle beams, such as plasma sintering, electron beam sintering, etc. However, the cost of such heat sources is too high, and the cost of equipment is in the Hundreds of thousands to millions of RMB

[0005] Induction heating generally inputs medium-frequency or high-frequency alternating current to the heating tube to generate induction current in the workpiece to achieve the purpose of heating and melting. This method has simple equipment and low cost. The device and method for rapidly forming metal parts by induction heating have not yet been seen. to report
